Red Flags Comment
<p>Basal facets are a very weak layer to be wary of as new snow accumulates and winter arrives. </p>

Several layers of basal facets and interspersed crusts from the ground to the new snow.

Unusual to see this many sun dogs together. Hopefully a sign of a big storm to come.

Snowpack

Instability Comment
<p>New snow will increase the load on the weak basal structure and increase avalanche danger.</p>

Fair amount of graupel in new snow. Variable snow depth secondary to wind before the storm. Areas on top of JP wind scoured to the ground with 3-4" of new snow on top. Widespread basal facets on all aspects that contained old snow. On north faces at 9,000' facets were cold, dry and non-cohesive. Basal facets were warm and cohesive at lower elevations on easterly facing slopes. Variable crusts, 4F to 1F, within the snowpack due wind, temperature and rain.
